प्रभाव और हमले की स्थितियाँअनुवाद हो रहा है…
The primary impact of CVE-2020-37221 is the ability for a local attacker to execute arbitrary code with the privileges of the Atomic Alarm Clock application. This could lead to complete system compromise, data theft, or the installation of malware. Attackers can leverage structured exception handling overwrite and encoded shellcode to bypass SafeSEH protections, making exploitation more reliable. Successful exploitation requires local access to the affected system, but the potential consequences are severe, potentially allowing attackers to escalate privileges and move laterally within the network if the application has elevated permissions.
